Basic MathEdit

C++ can be used to do basic math. The operators used in the basic math are listed in the table below.

Operator Operation
Arithmetic Operator   addition
  Substraction
  Multiplication
  Division
  Modulus
  Increment
  Decrement
Assignment Operator   " " is equivalent to " "
  " " is equivalent to " "
  " " is equivalent to " "
  " " is equivalent to " "
  " " is equivalent to " "
  " " is equivalent to " "
Comparison Operator   Equality
  Inequality
  Greater than
  Less than
  Greater than or equal to
  Less than or equal to
Logical Operator   Logical AND
  Logical OR
  Logical NOT

Basic math operators in C++ have some distinguishing features:

  • Bulleted list item
  • Bulleted list item
  • Bulleted list item

Part of Basic math operation is demonstrated in the C++ program below:

#include <iostream>;
using namespace std;

int main{
 int a=4, b=9, c=0;
 cout << "Addition result(a+b):"<<(a+b)<< endl;
 cout << "Multiplication result(a*b):"<<(a*b)<< endl;
 cout << "Multiplication & assign: a *=b(4*9) a="<< a*=b << endl;
 cout << "lesser comparision: a < b "<< (a<b) << "true"<< endl;
 cout << "And logic: (a && a)" << (a && a) << "(true)" << endl; 
}

Checking SizeEdit

The memory size of any variable can be discovered using the C++ sizeof operation.The sizeof operator syntax is look like this:

sizeof(var)

The sizeof operator is demonstrated in the program as follows:

#include <iostream>
using namespace std;

int main(){
}

Casting Data TypesEdit

Any data-types except "string" could be converted to another data type through "casting". Casting syntax in C++ looks like this:

variable-name=static-cast <data-type> variable-name

Casting with C++ form is demonstrated in the program as follows:

#include <iostream>
using namespace std;

int main(){
}
